Please write in English. However, based on your screenshot, I can suggest that you try to use the WIMGAPI engine instead of the WIMLIB engine for the backup portion of your operation. Just double-click the ZIPmagic icon in the DoubleSpace app to access the hidden settings window and choose the WIMGAPI engine.

The developer of the WIMLIB library suggested that you may be trying to use an external WIM file during the operation - this is not the case, right? You're re-compressing your C: partition with an external Undo Disk?
